Application filed May 2, 1899. Serial No. 715,320. (No model.)

To (tZZ whom it may concern:

Be it known that I, WILLIAM F. PARKER, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements indSeads forProtecting the Angles of Plastered falls; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to whichit appertains tomake and use the same.

My present invention relates to certain new and useful improvements inmetal corner strips or plates for protecting the angles of plasteredwalls, and more particularly to an ornamental bead-piece adapted to beattached to said corner-strip; and the invention also comprises a novelform of clip or anchor plate for securely holding the corner strip orplate in position.

It is the purpose of my invention to provide a simple form of bead-pieceadapted to be readily clamped to the corner strip or plate in suchmanner as to be held firmly in position, the said bead-piece being ofsuch a construction that it can be applied to corner strips or platesnew in use.

It is a further purpose of the invention to provide an improved form ofclip or holder for the cornenplate whereby to enable said clips orholders to be first secured to the angle of the wall and the cornerplate or strip afterward adjusted thereto, as desired.

M y invention is illustrated in the accompanying drawings, whereinFigure 1 is a perspective view of a part of a corner strip or platehaving one of my improved corner-bead pieces clamped thereon. Fig. :2 isa transverse sectional view of the same. Fig. 3 is'a perspective view ofa portion of a corner-bead, showing a modification of my invention. Fig.a is a transverse section of the headpiece shown in Fig. 3. Fig. 5 is atransverse sectional view showing a further modified form of thebead-piece. Fig. 6 is a perspective view of my improved form of clip.Fig. 7 is a sectional view of the clip.

Referring now to the drawings, the refer ence-nun1eral1 designates thecorner strip or plate, which is preferably of angular shape incross-section, as shown, and provided with a plurality ofplaster-receiving openings or slots.

The referenee-numeral 2 designates my improved form of corner-bead,which is preferably made of spring metal in the shape of a split tube,and when applied in position to the corner-strip it is simply expandedand slipped over the outer or free edge of said strip, as shown in thedrawings, and the springy nature of the tube will tend toclamp it firmlyto the opposite sides of the said strip. The corner-bead 2 is providedwith a plurality of plaster-reeeiving slots or recesses 3 along eachside, through which the plaster passes to the interior of the tube,where it again comes into contact with thatpart of the corner-platewithin the tube and firmly locks the said bead-piece in position. This Iconsider an important feature of my invention, for it will be thus seenthat the corner" bead is not only clamped to the plate by its ownelasticity, but is also locked by the plaster passing through therecesses therein and coming into intimate contact and engagement withthe corner plate or strip within the bead-piece, whereby a practicallyfirm and solid structure is provided. Ido not confine myself to anyparticular arrangement or location of the slots, for obviously theymaybe placed, as desired, at any point within the bead without departingfrom the spirit of my invention, and what I seek to cover by this patentis therefore a removable or independent eornenbead formed of a splittube provided with plaster-receiving slots or recesses and adapted to besprung upon or fitted over the edge of a corner-plate.

In the modified form of my invention shown in Fig. 5 I have illustratedthe corner-bead-I as being provided along each edge withrearwardly-extending flanges 5 5, which will lie flat upon the oppositesides of the corner plate, and thus retain the said head more securelyin position and alinement.

In Fig. i I have shown a still further 1nodification, and in this casethe bead-piece 0 is provided with rearwardly-extending flanges 7 7,

and each flange is provided with a plurality of short tongues or lips 8,which are adapted to enter the perforations or slots in thecornerstrip 1. By this construction it will be apparent that the plasterentering into the slots in the corner-strip will pack tightly around thesaid tongues or lips 8, and thus firmlylock the bead-piece in position.

My improved form of clip or holder comprises an angle-plate 9, providedwith one, two, or more inclined nailing slots or openings 10, said slotspermitting of an easy and ready adjustment of the clip or holder toaccommodate for suitable nailing-spaces between the plaster-joints ofpartitions made of tiling or other fireproof material. Projecting outfrom one face of the said angle-plate 10 is a vertically-arranged studor button 12, having an upwardly and outwardly inclined wall 13, formingan approximately wedge shaped opening between the said wall and angle-plate. In use the clips or holders are first secured to the angle ofthe wall at suitable points, as may be desired, and the corner plate orstrip is then applied thereto, the studs or buttons 12 passing throughthe slots in the corner plate or strip and the latter being then forceddownward, the metal between the perforations in the plate or strip beingthereby wedged between the inclined wall 13 and face of the clip orholder, whereby the plate will be held firmly in position.

I consider it of great importance that the bead piece or tube issupported throughout its entire length by a strip having a continuousbearing upon the bead, for this construction affords a firm and securefastening means for the bead-piece and one capable of holding the samerigidlyin position under all circumstances. It is likewise ofconsiderable advantage to provide a bead-piece that can be readilyapplied to corner plates or strips now upon the market.

WVhile I have herein shown and described the bead-piece as being made inthe form of a split tube, I wish it to be understood that Ido notconfine myself to any particular shape of tube so far as its externaldesign or crosssectional shape is concerned, for in practice Icontemplate giving the tube an ornamental appearance, so as to addgreatly to the richness and attractiveness of the corner or wall towhich it is applied.

What I claim, and desire to secure by Letters Patent, is

1. A bead-piece for protecting the angles of plastered walls consistingof a split tube having plaster-receiving openings or slots therein.

2. A bead-piece for protecting and ornamenting the angles of plasteredwalls, consisting of a split tube, and means for supporting saidbead-piece removed from the angle of the wall, said means having acontinuous bearing upon the inner wall of the tube throughout its entirelength.
